In Costa Rica I observed Bufo marinus feeding upon dog food several times...there were no insects moving about on the food to attract their attention. Co-workers at the Bronx Zoo have recorded their feeding upon salad set out for the tortoises that shared their exhibit. One book (Behler, Reptiles and Amphibians of the World, I believe) notes that an introduced population on New Zealand feeds largely upon vegetation during the dry season. Stomach analysis of individuals living near towns within their natural range revealed chicken bones and similar items...seemed too large to have been swallowed in association with feeding upon insects, but no way to be sure. Best, Frank
